Hola,como estas de Olanda.
Yo hablar mas a Anglais,estes mas bien por los otros personas a la paginas aqui.
It is really to bad to hear every time about species of animals that livi in country's and habitats where they shouldn't live.
I know it is very important to make sure that the native people have enough foodsurplies.
But what is often forgotten is,that this new introduced species will kill a lot of native species of fish in this case.
I can not even give a list of countries,in which are foreign species are introduced for one or the other reason,it is really a shame and to bad!!!
Only one example would be the foxes,introduced in Australia to wipe out the rabbits and rats that were introduced for hunting and unvoluntarely with ships(rats).
Now the foxes are killing the native animals,who have no response to this new predator who kills the more easy pickings of course.
One other example is the Nile Perch(very big growing and agressive cichlid)that was introduced to the Lake Victoria in eastern Africa.
This eating machine has probably wiped out 90% of the original species in this lake(mostly cichlids)that wre not even properly discoverd!!!
It would be better that some people put some energy in the problems how to get this kind of problems out of the natural systems,and restore the mistake that some people were making before,agree???
But i wish you luck with your study,it is not your mistake,but i hope you will take this issue into your study.
